Shia LaBeouf being hauled out of “Cabaret” by cops isn’t the only time 911 has been dialed at the show.

A night after LaBeouf’s bizarre arrest, Alan Cumming celebrated at the show with the cast to mark his 500 ¹/₂ performances in the musical, we hear.

The half is because when Cumming starred in the show in 1998, he ran offstage to blow his nose one night and, “I banged my head. I ran into a light. I made it through the first half of the show, and was all woozy.”
